Authorities in Mexico have launched an investigation after an anonymous call led them to find a drone carrying 3kg of methamphetamine, similar to the product in the critically acclaimed TV show Breaking Bad, near a US border crossing in San Ysidro.

They believe the drone crashed because the weight of the illegal drugs onboard had been too heavy for it.

Police in Tijuana said the drugs had been divided into six packets taped to the body of the drone.

This drone in particular was a prototype aircraft that could be given GPS co-ordinates and would then travel to a location autonomously without the need for a pilot to guide it.

Officials are examining the drone to see if they can trace who set it flying and where it began its journey.

The US Drug Enforcement Agency (DEA) reported in 2012, drones made more than 150 trips across the US and Mexico border.
